even after you unplug the brake sensors?

there is a little risk. The OP can also ask to borrow a new 790 LED panel and a set of new cable... We keep stock of these parts for our old models.

phone and light charger. If you want to have a decent front light, get a rechargeable light with its own battery then you can charge the light in the day.

I didn't ignore your comment. I did ask Andy about that at the time you posted about the Q70 kit. Andy told me he'll check with you and I heard no more about it. I had no problem with getting the block flush fitted on my Brompton. The bolts Andy sent with your kit may be of the wrong length. I...

if you wish to try a swap out, email support@wooshbikes.co.uk If you pay the postage, I can supply you with a sale or return replacement Lishui controller for your bike.

charging a Lithium-ion battery goes through two phases: CC or constant current phase, 2A for small capacity 36V (3A or 4A for larger capacity), the charger modulates the output voltage to keep the charging current constant. it is followed by CV constant voltage phase 42V for 36V batteries. The...

This is my Brompton with Bosch tool battery: The battery is lockable: I suppose you can open the battery case and fit something else like 21700-5000mAH cells for more distance but then, if you make your own battery, just as well fit it inside the controller bag. The only thing is the bag is...

your charger is standard 36V Lithium ion charger made by SANS Electronics. You can use another SANS charger with the same connector. They cost about £30-£40 on the net. SANS is about the best brand for this kind of products. I wouldn't be tempted to spend time and effort repairing a charger...

My house is on the Normandy coast and I need Eurostar to get back to London regularly to see the children and grandchildren. I can't see myself relocating to Paris. We have the use of a small flat in Paris but we are used to have a nice garden in Normandy.

we should blame the human tendency to believe that problems will somehow resolve themselves. They do but there is a time factor that people often underestimate. In the case of brexit, I fear that you and I may have died before the UK rejoins the single market. Tony Blair was on Radio 4...

I am well aware of the situation since day one of 2021. I may sell a bluetooth adapter for £25 to an eu customer who may get charged 15 euros in admin. Which export business can prosper if suffering that sort of extra cost? Customs union would help but really we need to rejoin the single market.

Your FETs seem OK. don't worry about being a newbie, everyone has to start somewhere. The problem is the fault is not clearcut. Your motor still spins up. You may spend a lot of time testing various components without coming to any concrete diagnosis. Show us a pictures of the connectors at the...

you have a 790 analog LED panel. You can see the battery level (4 LEDs). Is the bike still rideable? if it is not, then the controller is suspect. If it is, then check that the battery level does not lose more than 1 LED when going uphill. It's difficult for us to help you because your kit is...

not without proven working LCD and cable.

If the LCD reports error 21 then I would check the motor cable. When one of the FETs goes, you should see a short between one of the phase wires and BAT+ or BAT- (you have to remove the battery before testing). If the FETs are working but apparently not functioning properly, you'll need an...

you can check the MOSFETs first before buying anything. The symptoms are not clearcut to come to any conclusion. Not in common Lishui controllers. The manufacturer can request specific features to be programmed in though, like reduced power if the motor stalls or if someone disconnects the...

I agree, 6 pin connector: the motor has no Hall, just phase wires and speed sensor. In that case, if the motor does not have much power then you will have to check your controller. Most Lishui controllers will work with and without Hall.

the visible Hall sensor in the middle of the board is the speed sensor. There are 3 Hall sensors below the circuit board. You should see their legs on the soldering pads at the edge of the board. You can check the Hall signal by rotating the motor slowly. I usually clamp the motor axle onto a...

you have demonstrated that the noise comes from the main gear, not the blue gear. You will have to remove the main gear, check for damage, regrease and re-assemble. There are a number of ballbearings, one of them is possibly damaged by water ingress.

the police have indicated since 2015 that they are not interested in whether you have a throttle on your bike or not. It's only the Spanish and French gendarmerie would be looking for them. In UK law, if you have a twist and go throttle, it should be limited to 6km/h. Non twist and go throttle...
